SAS Object Spawner script wait a key

herborfer — Fri, 15 Jan 2021 09:37:05 GMT

Hi all;

I am trying to make an entry in Rundeck to stop and start SAS Object Spawner by operator if it is NOT UP after a weekly start.

My point is that SAS Object Spawner is asking for a key and that is a mess.

I had tried to comment the wait commands, but it does not work.

Any idea?

This is the current Object Spawner script:

#!/bin/sh -p
#
# ObjectSpawner.sh
#
# syslog Starts the SAS Object Spawner
#

# Uncomment the set -x to run in debug mode
# set -x

# Source level_env
. `dirname $0`/../level_env.sh

CONFIGDIR=$LEVEL_ROOT/ObjectSpawner

LOGSDIR=/work/sas/Lev4/ObjectSpawner/Logs
SASENV=$SASROOT/bin/sasenv
OMRCFG=$LEVEL_ROOT/ObjectSpawner/metadataConfig.xml
SPWNNAME="Object Spawner - sas94-t"
SERVERUSER=sasadm
CMD_OPTIONS=" -dnsmatch sas94-t.internal.epo.org -sspi "
COMMAND="$SASROOT/utilities/bin/objspawn"
SCRIPT=`basename $0`

if [ "$SAS_INSTALL_ROOT" = "" ] ; then
SAS_INSTALL_ROOT=$SASROOT
export SAS_INSTALL_ROOT
fi

# Are we super user
if id | grep "^uid=0(" >/dev/null 2>&1 ; then
root=1
else
root=0
fi

# If there is a keytab present for the object spawner, export it here
if [ -f "$CONFIGDIR/objspawn.keytab" ]; then
KRB5_CLIENT_KTNAME="$CONFIGDIR/objspawn.keytab"
export KRB5_CLIENT_KTNAME
fi

# Get argument
case "$1" in
start | -start)
if [ -f $CONFIGDIR/$SERVER_PID_FILE_NAME ]; then
pid=`cat $CONFIGDIR/$SERVER_PID_FILE_NAME`
kill -0 $pid > /dev/null 2>&1
if [ $? -eq 0 ]; then
echo "Spawner is already running (pid $pid)"
exit 0
fi
rm $CONFIGDIR/$SERVER_PID_FILE_NAME
fi
if [ $root -eq 1 ]; then
su - $SERVERUSER -c "$CONFIGDIR/$SCRIPT start2_tag &"
else
$CONFIGDIR/$SCRIPT start2_tag &
fi
;;
start2_tag)
cd $CONFIGDIR
. $SASENV
SASROOT=$SASROOT
export SASROOT

# Source usermods file
. $CONFIGDIR/ObjectSpawner_usermods.sh

eval "nohup $COMMAND $CMD_OPTIONS -sasSpawnerCn \"$SPWNNAME\" -xmlconfigfile $OMRCFG -logconfigloc $CONFIGDIR/logconfig.xml ${USERMODS}> $LOGSDIR/ObjectSpawner_console_sas94-t.log 2>&1 &"
pid=$!
echo $pid > $CONFIGDIR/$SERVER_PID_FILE_NAME
echo "Spawner is started (pid $pid)..."
# Trap signals 9 and 15 and pass on to child process
trap 'kill $pid' 2 3 15
wait $!
rm "$CONFIGDIR/$SERVER_PID_FILE_NAME"
echo "Spawner is stopped"
echo "Log files are located at: $LOGSDIR"
;;

if [ -f $CONFIGDIR/$SERVER_PID_FILE_NAME ]; then
pid=`cat $CONFIGDIR/$SERVER_PID_FILE_NAME`
kill $pid
if [ $? -ne 0 ]; then
echo "pid: $pid"
fi
else
echo "Spawner is stopped"
fi
;;
status | -status)
if [ -f $CONFIGDIR/$SERVER_PID_FILE_NAME ]; then
pid=`cat $CONFIGDIR/$SERVER_PID_FILE_NAME`
kill -0 $pid > /dev/null 2>&1
if [ $? -eq 0 ]; then
echo "Spawner is started (pid $pid)"
else
echo "Spawner is stopped"
fi
else
echo "Spawner is stopped"
fi
;;
restart | -restart)
$0 stop
if [ $? -eq 0 ]; then
sleep 5
$0 start

Hi @herborfer

What do you mean by asking for a key? parameter? sorry I did not get it. Could you share how are you trying to call the spawner command via RunDeck?

Before Rundeck, when we run the script on the console ( by "sh ObjectSpawner.sh" or ./ObjectSpawner.sh on the proper path ) it waits for key to end. When I press INTRO then it goes to the end.
That's a problem to be included in Rundeck.

Ok, I get what you are referring to. How about using nohup before the start/stop command whichever way you are using it?

nohup ./ObjectSpawner.sh stop

nohup ./ObjectSpawner.sh start

it create a nohup.out file.

Yes it would just output everything to a file but it can solve the problem of hitting a key for script to exit or complete.

Redirect the outputs to the bit bucket:

nohup ./ObjectSpawner.sh stop >/dev/null 2>&1

nohup ./ObjectSpawner.sh start >/dev/null 2>&1
